An alkaline secondary battery which is characterized in that it comprises,
a positive electrode containing nickel hydroxide having a value of
0.8.degree. or more in the half-width of a peak in the (101) plane
thereof as measured by X-ray powder diffraction (2.theta.) using
Cu--K.alpha. ray, and 4.0 to 15% by weight of at least one material
selected from the group consisting of zinc and zinc compounds, and an
alkali electrolyte, the ratio of which to theoretical capacity of the
positive electrode being 0.7 to 2.0 cm.sup.3/Ah, the weight of the at
least one material being one calculated as zinc element and based on the
weight of the nickel hydroxide.
